I worked with a guy a while back who had worked for Pacific Wings. He quit a few months after being out there. He said that the SIC position is pretty much a fill in wherever they need you job. You will fly right seat, but you will also work dispatch, ramp, etc. Also, the cost of living is so high that he was living with five other guys in a three bedroom place, and they still barely paid the rent...you still have to eat and pay whatever other bills you have. He told me that the captains make more, but they still are well below average. They do hire direct entry captains at times, but at the 1200 hour mark, and by then I am sure that you would have other places in mind that would be a much better environment.
They also used to make you pay for your ride out for the interview and then pay again to get there for training. Something to consider as well.
